We report operation and characterization of a lab-assembled single-photon detector based on commercial silicon avalanche photodiodes PerkinElmer C30902SH, C30921SH. Dark count rate as low as 5 Hz was achieved by cooling the photodiodes down to -80 C. While afterpulsing increased as the photodiode temperature was decreased, total afterpulse probability did not become significant due to detectors relatively long deadtime in a passively-quenched scheme. We measured photon detection efficiency higher than 50% at 806 nm.
